摘要： A novel and improved drawing desk is provided which can be folded between a storage position and a drawing position. The desk has a center leg which raises from a first end located on the floor to a second end which is pivotally attached to an end leg. By pivotally attaching the center and end legs, the longitudinal axes of the center leg and end leg can be positioned so that they are substantially parallel in the storage position and substantially transverse in the drawing position. An easel is pivotally attached to the center leg for receiving a removable drawing board. A seat assembly, pivotally attached to the center leg, has a protruding seat arm adapted to engage a seat slot disposed in the center leg and a device for adjusting the position of the seat in order to accommodate users of different sizes. In the preferred embodiment, the adjusting device comprises the seat leg having a bottom end which is adapted to engage a plurality of openings disposed along the center leg. By aligning the longitudinal axes of the seat, the seat leg, the end leg, easel and the center leg in the storage position, the drawing desk is relatively compact so that numerous desks may be stored in a small area.
